Abstract

See full text

Gas mixture used for ventilation of passengers and crew in emergency situations. Depending on the density altitude, it has 7±5% CO2 at 15,000 ft flying altitude increasing to 17±5% CO2 at 30,000 ft flying altitude. The carbon dioxide improves the bioavailability of oxygen in the body. The gas mixture is produced by additive dosage of CO2 to either pure O2 or to a gas mixture having a fraction of N2 and a fraction of O2. The method for ensuring good ventilation in case of loss of cabin pressure, or generally in case of hyperventilation, involves making the gas mixture above available via respiration masks. The use of such a gas mixture also for ensuring good ventilation of people with limited mobility, if such ventilation is required. The prescribed amount of onboard oxygen for aircraft can thus be reduced and flight routes leading directly over high-altitude terrain may be taken.
